Since he is in space @NASAWebb has received 5 hits. -Impacts are unavoidable. -They will continue to happen. -The @NASA he took it for granted and the telescope was designed accordingly.

What was the time estimate for everything to be done?

At the JWST town hall at #AAS240, Scott Friedman of STScI says 6 of 17 JWST observing modes have now been declared science ready (2 of them earlier today.) By end of next week should have 13 of 17 modes commissioned.

 Now if that redneck solar system would just quit taking potshots at it.

Those who danced were thought to be quite insane by those who couldn't hear the music.

 Past the half way point on instrument commissioning. Can't wait to see coronagraph results.

Reactions from people who have seen some of the images that are going to be released on July 12th.

https://www.foxnews.com/science/nasa-webb-telescopes-first-light-images

"NASA’s deputy administrator, Pam Melroy, said the "first light" images "moved me, as a scientist, as an engineer, and as a human being." "First light" generally refers to the first time a telescope is used to make scientific observations after it has undergone tests and calibrations.

Thomas Zurbuchen, NASA’s scientific programs leader said during a Wednesday news conference he was nearly moved to tears by the images."

With commissioning of the James Webb Space Telescope nearly complete, project officials and NASA leadership promise the telescope’s first images will stun scientists and the public alike.

During a media event at the Space Telescope Science Institute (STScI) here June 29, project managers and scientists said the telescope is already collecting “early release observations” that NASA, along with the European Space Agency and Canadian Space Agency, will unveil July 12. Those observations are taking place as engineers finish preparing the telescope for routine science observations, with 15 of its 17 observing modes now commissioned.

JWST’s technical performance continues to exceed expectations. Lee Feinberg, JWST optical telescope element manager at NASA’s Goddard Space Flight Center, that the telescope had a requirement that its resolution be diffraction limited — that is, its sharpness limited only by the laws of physics — at wavelengths as short as 2 microns. He said the telescope was in fact diffraction limited down to 1.1 microns.

Preview image released from Webb's Fine Guidance Sensor.

https://blogs.nasa.gov/webb/2022/07/06/webbs-fine-guidance-sensor-provides-a-preview/

https://blogs.nasa.gov/webb/wp-content/uploads/sites/326/2022/07/fgs2_1445_20220601_TS_newflat_JRstretch_crop-2048x1954.jpg

"This Fine Guidance Sensor test image was acquired in parallel with NIRCam imaging of the star HD147980 over a period of eight days at the beginning of May. This engineering image represents a total of 32 hours of exposure time at several overlapping pointings of the Guider 2 channel. The observations were not optimized for detection of faint objects, but nevertheless the image captures extremely faint objects and is, for now, the deepest image of the infrared sky. The unfiltered wavelength response of the guider, from 0.6 to 5 micrometers, helps provide this extreme sensitivity. The image is mono-chromatic and is displayed in false color with white-yellow-orange-red representing the progression from brightest to dimmest. The bright star (at 9.3 magnitude) on the right hand edge is 2MASS 16235798+2826079. There are only a handful of stars in this image – distinguished by their diffraction spikes. The rest of the objects are thousands of faint galaxies, some in the nearby universe, but many, many more in the distant universe. Credit: NASA, CSA, and FGS team."

 The blog has been updated along with a fuzzy sample from NIRSpec’s multi-object spectroscopy mode.

 A list of what we can expect Tuesday.
https://www.nasa.gov/feature/goddard/2022/nasa-shares-list-of-cosmic-targets-for-webb-telescope-s-first-images

"Carina Nebula. The Carina Nebula is one of the largest and brightest nebulae in the sky, located approximately 7,600 light-years away in the southern constellation Carina. Nebulae are stellar nurseries where stars form. The Carina Nebula is home to many massive stars, several times larger than the Sun.
WASP-96 b (spectrum). WASP-96 b is a giant planet outside our solar system, composed mainly of gas. The planet, located nearly 1,150 light-years from Earth, orbits its star every 3.4 days. It has about half the mass of Jupiter, and its discovery was announced in 2014.
Southern Ring Nebula. The Southern Ring, or “Eight-Burst” nebula, is a planetary nebula – an expanding cloud of gas, surrounding a dying star. It is nearly half a light-year in diameter and is located approximately 2,000 light years away from Earth.
Stephan’s Quintet: About 290 million light-years away, Stephan’s Quintet is located in the constellation Pegasus. It is notable for being the first compact galaxy group ever discovered in 1877. Four of the five galaxies within the quintet are locked in a cosmic dance of repeated close encounters.
SMACS 0723: Massive foreground galaxy clusters magnify and distort the light of objects behind them, permitting a deep field view into both the extremely distant and intrinsically faint galaxy populations."
